While working on an outdoor Christmas project using NeoPixel strips, I ran into a small problem. I wanted to be able to have several groups of pixels many feet apart from each other, but still all synchronized and controlled by the same single controller. I worked out a way to use RS-485 drivers to push the data through CAT5 cable, along with using small, low cost DC/DC converters to distribute the power to the remote strips. I was able to control a full 5 meter roll of NeoPixels through 100 feet of CAT5 using the technique, more than enough for my project.

Thank you to all of you for your excellent blog and forum posts, without which my lurking (and learning) would not be possible!
